i Application iiled December 5, 1882. (No model.)

.To @ZZ whom, t may concern: l

Beit known that I, JOHN L. GILL, Jr., of

Allegheny city, in the county of Allegheny y and State of Pennsylvania, have invented a new and useful Improvement'in Dump-Cars;

and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part oi' this specification, in .which- Figure l is a bottom plan view of the frame of my improved dump-car. Fig. 2 is a side elevation. Fig. 3 is an`end view.

a section on the Vline x x of Fig. 2.

Like letters of reference indicate like parts in each.

To enable others skilled inthe art to make Fig. /l is and use my improvement, I will now describe its construction. i

The frame is composed of side sills, a, center or draft bar sills, b, short sills e, end timbers, (Z, bolsters e, and cross-ties f, of substantially the usual construction.

On lthe under sides of the sills c and b are subsills g, which extendbetween the trucks h and beyondthe dumpiopenings i. The dumpopenings Z are each fitted with doors i,which are hinged at the sides, and at the center are supported by chains i. The chains Z2 are operated by windingshafts i, controlled by pawls and ratchets t, in the usual way.` The cross-ties f are bolted to the under side of the subsills g, which brings them each lower than in the old construction, in which they were bolted directly to theside sills, a. The sides ofthe car are composed of planks 7c, of any desired number, which are secured together and to the car in the following manner: On the upper endsbf the bolts Z, which extend through the side sills, are lat metallic straps Z', and on the outside of the planks are stakes m, which are inserted in sockets m', bolted to the outside of the sills a. Bolts m2 extend through the straps Z', planks k, and stakes m, and are secured by suitable nuts and washers. In addition to this I further secure the planks L by means of other bolts, n, (seel Fig.V 2,) which extend vertically through the side sills, subsills, and the planks. This construction en- 4 5o ablesime to make the sides of the hopper of any suitable height and of great strength and durability.

It is the design of this invention to obtain a long car of great strength and proportionately increased capacity, and one which will enable the carto be unloaded more easily and rapidly and without the necessity of shoveling. For this purpose I have the double hopper, which is formed by the inclined bottoms o o, (see dotted lines, Fig. 2,) which extend from the 6o ends o of the car to the adjacent cross-tie f, and in the center of the car between the two dump-openings@- by a double incline, p, (see dotted lines, Fig. 2,) the. ends of which extend down to the inner 'crossties, fj The bolting 65'l of the cross-tiesf to the under side ofthe subsills g enables me to extend the inclinedbottoms o below the main sills a and b andto give them a greater pitch. The additional room or carrying capacity thus obtained by extending the bottom of the car below the main sills more than compensates for a slight loss of room at the ends of the car underl the inclined floors o, and this construction actually increases the carrying capacity of the car over that of one of the same size made according to former constructions. 'Ihe addition of the subsills below the main sills enables the `inclines which are arranged between the dump-openings to be given such a steep pitch as will ei'i'ectually 8o prevent the lodgment of any portion of the load thereon, which is a material matter in cars having several dump-openings. A great advantage in the use of the subsill, in addition to that of increasing the capacity of the car and the pitch of the iioor, is the fact that they give additional sustaining strength to the frame of the car, and by applying them to the center or draw-bar sills I strengthen to resist the butting strains occurringin the shifting of trains.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. In a dump-car, the combination, with the main sills, of subsills bolted to the under side of the same, and cross-ties bolted to the under sides of the subsill, substantially as and for the purposes described.

2. In a double dump-car having inclines between the dump-openings, the combination, Ioo

with the main sills, of subsills bolted to the under side of the same, substantially as and for the purposes described.

` 3. In a dump-car, the combination of subsills bolted to the under side of the main sills, cross-ties bolted to the under side of the subsills, and inclined floors extending from the ends of the car to the adjacent subsills, substantially as and for thepurposes described.

4. In a dump-car, the combination of subsills secured to the under side ofthe main sills, cross-ties secured to the under side of the subsills, a double hopper composed of inclined bottoms extending from the ends of the car to the adjacent subsills, and a central double in- I5 eline placed between the two dump-openings, substantially as and for the purposes described. In testimony whereof I have hereunto set my hand this 22d day of November, A. D. 1882'. f
